When a star burns out and collapses under its own weight, the space around it crumples into a black hole. At the center, according to textbooks, lurks a singularity — a point where density becomes infinite and the laws of physics break down.
You can poke a pencil through a folded sheet of paper, and the path between two points becomes shorter. That's roughly how the idea of a wormhole works: a tunnel in space connecting distant regions.
A magnetic field can hold a star against complete collapse: that's the idea behind a new kind of black hole. Instead of the usual point of infinite density, inside there is a field that prevents space from crunching down to zero. It's like a spring: the harder you squeeze, the more it pushes back.
In 1973, Jacob Bekenstein proposed that black hole possess entropy — a measure of hidden disorder. Stephen Hawking later confirmed this by adding radiation, but the microscopic origin of entropy remained obscure.
